We have an evaluation board for AD9959 DDS.  After examining the power supply pins on the board, 2 of them (DVDD and VCC_USB) are showing short with the ground. If I measure the resistance between the pins and ground I get 4.7 ohm, 7 ohm and 60 ohm for DVDD, VCC_USB and DVDD_IO respectively.  I also checked the current drawn by the board after applying a small voltage to the power pins. The current drawn is consistent with the measured resistance.
